HP 35s Calculator

HP's week ended with a commemoration on Friday, celebrating the 35th year of the company's scientific calculators with the HP 35s. Built to closely resemble the original model, it also represents one of the most advanced small-screen calculators in 2007, HP says. 30KB of memory gives it enough memory for larger macro programming and 800 storage slots. It can also perform as many as 100 different math operations and input of values in either HP's custom format or Reverse Polish Notation as well as through conventional algebra.

The two-line calculator should be available just as school begins in late summer and will sell both at campus bookstores and general retailers for $60, including a specialized carrying pouch that keeps the device safe in a backpack or bag.
